The Domain Name System (DNS) is a giant directory that helps translate domain names – the human-friendly, recognisable and memorable addresses that web users type into browsers – into IP addresses (a series of numbers and in a dotted decimal format) to help locate the hosting website. The system is based upon a huge network of DNS servers spread across the world.
Of course, the DNS system is essential for the accurate and timely location of the desired website when a web user makes a search in a browser. It’s one of the key technologies that underpins the internet.
